vRD/POL Inductor

Specifications subject to change without notice.

800.729.2099 tel

The ICL 701-1 using IKOR’s coupled inductor technology solves the most pressing problem facing IA-32 VRDs

and VRMs. This patented technology solves the trade-off between efficiencyand elimination of bulk capacitors

by dramatically lowering the VRM output inductance while using industry-standard components and relatively

low switching frequencies. This technology provides superior transient response performance to higher

frequency solutions due to the unique method of coupling between phases, and enables high-current designs

with little or no electrolytic output bypass capacitance. The ICL701-1 coupled inductor can be used in both

VRD and module VRM applications. Its small size and low height make it possible to design high-density VRMs

and to fit the inductors very close to the CPU socket in VRD applications. This device can also be used in high-

current System VRM (SVRM) applications where small size, high efficiency, and low total BOM cost is critical.
